Meaning and Usage
The word "幹" (みき) primarily means the trunk of a tree, the main woody stem that supports branches and leaves. It is a concrete noun often used in natural contexts.
However, "幹" is also used metaphorically to refer to the core or main part of something, such as the central members of an organization or the essential part of a project. In this sense, it often appears in compound words like "幹部" (かんぶ, executives or key members).
Common Collocations
- 幹部 (かんぶ): executives, key members of an organization
- 幹線 (かんせん): main line (e.g., railway, road)
- 幹事 (かんじ): organizer, coordinator
- 幹となる: to be the core or main part
Usage Notes
When used literally, "幹" refers to the physical trunk of a tree and is a straightforward noun. When used figuratively, it implies importance and centrality within a group or system.
Learners should be careful not to confuse "幹" with "木" (tree) or "枝" (branch). Also, "幹" as a metaphor is often found in formal or business contexts, especially in compounds.
Register and Politeness
"幹" itself is neutral and can be used in both casual and formal contexts, but its compounds like "幹部" tend to appear in formal or business settings.
